function net = mdnunpak(net, w)
%MDNUNPAK Separates weights vector into weight and bias matrices. 
%
%	Description
%	NET = MDNUNPAK(NET, W) takes an mdn network data structure NET and  a
%	weight vector W, and returns a network data structure identical to
%	the input network, except that the weights in the MLP sub-structure
%	are set to the corresponding elements of W.
